ADSP-21469
ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 14 may cause perma-
nent damage to the device. These are stress ratings only;
functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

ESD
(electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid
performance degradation or loss of functionality.
